The Scottoiler Breather Cap is an essential component designed to maintain the integrity of the reservoir by preventing dirt ingress while facilitating necessary air circulation. This cap features a deliberate indent on its side, which is a critical design aspect to prevent overtightening and the potential for vacuum lock, ensuring the system operates flawlessly.Key features to consider:Deliberate Indent Design: The intentional indent on the side of the breather cap is ingeniously designed to prevent overtightening, averting any risk of vacuum lock that could compromise system functionality, thereby ensuring the reservoir breathes efficiently without compromising on cleanliness or performance.Dirt Ingress Prevention: This cap is meticulously engineered to form a barrier against dirt, protecting the reservoir's internal environment from contamination, which is essential for maintaining optimal system performance and prolonging the life of the components involved.Air Circulation Facilita
